[U-Boot] [PATCH 2/3] board: tbs2910: Convert pci to driver model

[Soeren Moch]

So we can get rid of legacy pci config code.

PCI_PNP is not required for this board, remove it to reduce the size of the
u-boot binary.

DM_PCI does not start the host controller automatically anymore. Do so
in preboot instead.
